When a process starts a new process in a computer program, the calling parent process and the called child process are called. Each child process returns a return code (the return code) to the parent process upon which it can inform the child process. This can tell whether the process was running correctly or whether an error occurred. Further qualifying data are possible, for example to warnings or incomplete processing. On the basis of this feedback, the parent process can decide on the further program sequence. Implementation Edit source text Edit source text Single-level Edit source text
